To titl whom Az5 may concor/i.'

lie it known 'that i, hline itnnniissoiv, a subject ot the ng ot Sweden,residing at lristinediainn, mveden, have invented a new and usefulimprovement in l'lolders tor ,i lister Litakes tor Freight Ylvlehicles,ol" which the Alfoliowing is a speciiication.

The present invention relates to a holder tor bolster stakes such as areused on treight vehicles, tor instance ireight cars and other waggons orcarts, drags and the like, for retaining the load on the vehicle,particularlvi7 when the load consists oif logs or the like. its is wellknown, a number ol" bolster stakes are used in such cases on the twolongitudinal sides oi' the ear or other vehicle used. it has previouslybeen proposed to t .re said bolster stakes in holders, each consistingoi two members movable relativelyY to one another, and one oit whichmembers may be moved aside in such inanner that the stake may be movedlaterally out 'from the car without having to be moved longitudinally.in this manner it is possible rapidly to release the stakes at one sideot the car, or at both sides desir'ed, and in this manner considerablyto facilitate the unloading` oi the car. Such holders as heretoforeused, however, are veryv complicated and therefore expensive, ior whichreasons theyY have not yet attained anyY extensive use in practice.

lhe purpose oit the present invention is to avoid these disadvantages.The invention consists broadly in that one member cil each holderconsists oi a socket bracket or the like secured to the trame ot thecar, and the two shanks or extended cheek-pieces ot which enclose astake inserted in the holder on two opposite sides, the other member ol"the holder consisting ot a locking lever which is pivoted to the trameot the car inside the bracket in such manner that it is capable orturning on an axis parallel with the longitudinal direction of the stakeinserted in the holder, and the outer portion oiE which is bent 'to theshape oit' a hook in such manner that it may grip around or engage theouter side ot the stake inserted in the socket. in this manner anekceedingly simple and reliable holder is obtained in which least thegreater portion ot the pressure oi" the stake on the locking lever istaken up by 'the pivot of said lever which may easilyv be madesutliciently strong tor resisting said pressure. in practice it willSerial lilo.

sometimes be suitable to use two such holders, one above the other, toreach stake, in which case the inner portions ot the locking levers ot'said holders, i. e. the arms oif said levers on the inner side oit theturning anis may be joined to torni a common lever arm.

in the accompanying drawings a suitable embodiment oi' the inventionapplied t0 a railwab-f' car, is shown by way of example. iiig. l showsthe holder and its attachment to the licor ot the car, viewed in thelongitudinal direction ot the car. Fig. 2 shows the holder viewed fromthe side ot the oar, and shows the stake inserted into place, and showsa" horizontal section on the line lli-lill in Fig. 2. Fig. et shows theholder in open position and viewed trom one side ot the car, the stakebeing removed, and llig. shows a horizontal section'on the line v-V inFig. 4.

ln the embodiment illustrated in the drawing each stake l is secured bymeans of two holders which are supported one above the other at the edgeot the car floor. Both holders are rigidi;7 secured to the car frame abelow the car iioor. 'lhe stake l is shown in the drawing as being oi'tubular cross-section in a usual manner, and is provided with a bottompin itor inserting the stake in rdinary immovable holders, but it willbe understood that the present holder may be adapted to beused for anyother type ot stake. Each holder consists oit an open socket bracket 6which is `attached in suitable manner to the trame 4:, and of a lockinglever 2 pivoted to said trarne by means of a rivet or pin 5 on theinside of the bracket 6, the outer portion of said lever beinghook-shaped, as shown in F ig. 3, in such manner that it is capable togrip around the outer side o1e a stake inserted in the bracket, so thatthe greater portion oit the pressure oit' the stake against the lockinglever 2 is taken up by the pin 5. The lower end of the stake l restsupon a plate 16 secured to the lower bracket 6. TWhen, as illustrated inthe drawing, the stake l is provided with a bottom pin :tor enabling thestake to be inserted in the ordinary iniinovable holders the plate lo isprovided with a slot opening outwards for receiving said pin, as clearlyshown in Figs. 3 and 5.

rihe inner arms ot the locking levers 2 of the two holders are joinedtogether on the inner side ol' the turning axis 5 of the levers,

to form a common lever arm 3, as shown in Figs. l and 2. Each such leverarm 3 is pivot-ally and slidably connected to a slidable rod l0extending along the entire length ot the car and by means of Which alllever arms 3 and thus all locking levers 2 on one side of the oar may beturned to locking position. The movement of the rod 10 may be effectedby means ot a suitable lever or the like, not shown in the drawing, atone end'oic the car.

lVhen the stakes l are to be attached to the car before loading the samethe locking levers are turned to locking position by moving the rod 10by means of its actuating` lever, Which is then prefereably secured insuitable manner in such position. rllhe stakes are afterwards insertedfrom above into the holders. Vhen the car has been loaded the upper endsof the stakes may suitably be connected in pairs by means ot chainsacross the load on the car, in order to secure the load.

The unloading may be effected to one side only, or to both sides, ascircumstances may demand. In the former case it is ot' course onlynecessary to releasel the stakes l on one side of the car. lhen the caris to be unloaded in this manner the rod lO is released and is moved tothe right in Figs. 2 and 3, when all the locking levers Q are turnedinwards underneath the car -floor to the position shown in Figs. l and5. All stakes l on such side oit the car are thus released trom theirrespective holders and, While hanging' in the chains connecting theirupper ends With the corresponding stakes on the opposite side of thecar, Will swing upwards and out-Wards owing to the pressure ot the logs.A great many of the logs will then roll oil' the car owing to their ownweight` and the remaining logs may attervvards easily be rolled oit inthe saine manner, and the load may thus be discharged very rapidly.

Again, it it is desired to unload towards both sides in which case thereshould of course be provided one actuating rod l0 for the holders oneach side ot the car, the holders are operated in the same manner asabove described, and both sides may be operated simultaneously, or oneatter the other.

The embodiment above described and illustrated in the drawings is otcourse only to be regarded as an example ot' the invention, and it willbe understood that it is capable ot modification in sev-eral respect-sWithout departing troni the principle and scope oic the invention. Forinstance, in certain cases it will be suilicient to provide only oneholder for each stake, provided that jrhe holder is given such heightand its locking lever such thickness that the stake obtains a securesupport.

l claim:

l. ln a bolster stake holder, the combination of a laterally open socketbracket having cheek-pieces adapt-ed to enclose a stake trom tivoopposite sides, and a locking lever pivoted on the inside ot saidbracket and capable oi' turning on an axis substantially parallel withthe longitudinal direction et a stake inserted in said bracket, theouter arm of said lever being hook-shaped and adapted to engage theouter side ot such stake.

2. The combination of tvvo laterally open socket brackets haviiwcheek-pieces adapt-ed to enclose av stake from tivo opposite sides. saidbrackets being positioned one above the other, and tivo locking leverspivoted on the inside of said brackets and capable of turning on an axissubstantially parallel with the longitudinal direction ot a stakeinserted in said brackets, the outer arms ot said levers beinghook-shaped and adapted to engage the outer side ot such stake, and theinner arms ot said levers being joined to Yform a common arm.
